Look time has already proved over and over that the bigger hardware, graphical beast is not always the better choice or even the winner for that matter...Examples include
Nintendo NES won over NEC Turbo Grafx 16
Super Nes won over Atari Jaguar
Sony Playstation won over Nintendo 64
Sony PS-2 won over Microsoft Xbox
Now the most recent example of history repeating itself is the Nintendo Wii over the 360 and PS3.
